For all this who have yet to see both the original and the remake . . .

Both are superb! Seriously! Usually, remakes (especially American remakes) are horrendous, but thankfully this was not the case.

Although, Let the Right One In definitely stands apart from Let Me In in a variety of ways (most notably, the sombre tone), the same can be applied vice-versa. What I especially loved about the remake was the intense focus between the main characters; not that that doesn't exist in the original, but the original incorporates side-characters and sub-plots, whereas the remake avoids a lot of those seemingly unnecessary elements. Both Eli and Abby are excellent characters (though Eli is far more vampiric and alluring, whereas Abby is more monstrous), and Oskar and Owen are equally comparable. And personally, I like the bullies in the American version.

Anyway, both are excellent and stand apart from one another in a number of ways. Yet, if hard pressed, I would still have to choose the original. Nevertheless, Let Me In is awesome.
